and sought to discover which ratio of an acid and base reaction produced the most amount of carbon dioxide gas (CO2) without leaving leftover reactants. 5 varying amounts of bases were added to a constant amount of acid (10 ml) to better understand which ratio was the most efficient. RESULTS Data collected from the lab suggests that the ratio of acid to base that produced the most carbon dioxide gas (CO2) was 1:0.5. This means that for every one mole of acid‚ 0.5 moles of base would be added. The

the reaction of butanols with hydrobromic acid. Before the lab began we discussed and proposed mechanisms. (see “Mechanisms”) To begin this experiment we calculated how much of each material we were going to be using‚ and the numbers we chose to use differed from our reference text slightly. We used 6.5 mL of our assigned butanol and only 4 mL of sulfuric acid. Going back to our reaction mechanisms‚ we were looking at SN1 and SN2 reactions‚ so we of course used the hydrobromic acid as our acid catalyst

Title: Effect of a Catalyst on Reaction Rate II. Introduction: The basis of the experiment is the enzyme; an enzyme is a biological molecule that acts as a highly selective catalyst. By combining with a substrate‚ an enzyme is able to create a new product that helps the body function. (Ex. Lactose/Lactase) A substrate is a molecule an enzyme acts upon‚ the two combine at an area called an active site. This active site allows induced fit which allows the reaction to occur and a new product to be

There are many factors that would affect human resource management. However the main four are considered to be: • Political climate • Economic climate • Company strategies • Technological developments Political Climate The political climate can have a great affect on any business and subsequent business departments such as human resource management. If the government decides on spending cuts or increasing taxes on businesses then this will dramatically affect the running of the business

Assignment 1 UNIT 1 Question 1 (5 marks): Discuss the rate-limiting factor. Why is it important to consider when studying exercise physiology and training? Provide one example to clarify your understanding. The rate-limiting factor is the “step” that limits performances (the “slow step”). If we know the rate-limiting step in a certain physiological pathway or training situation‚ we can manipulate the factors of this step to change and increase the rate of the pathway. This will improve overall training

Antacid tablets are used to relieve heartburn and neutralise stomach acid. Planning Aim To determine how the surface area of the tablets affects the rate of the reaction. To determine which form of tablets gives the biggest surface area resulting in the fastest reaction rate. Investigation question: What is the relationship between the total surface area of the tablets and the rate of the reaction? Hypothesis: The rate of reaction will be the fastest when the tablets crushed into powder as there

Contrastive Analysis in the Classroom 1. Introduction Contrastive analysis is a very controversial field of applied linguistics‚ especially in regard to its role in the language teaching process. There have been times when comparing languages was considered to be the very foundation of language teaching‚ and those when any reference to the mother tongue was absolutely forbidden. The aim of this paper is to show some misconceptions about contrastive linguistics in general and present the
